The cybersecurity landscape has reached a critical inflection point. Frontier models, such as Anthropic Mythos, are currently dominating security conversations, signalling a profound shift in adversarial capabilities. As artificial intelligence becomes deeply integrated into the hacker’s toolkit, organisations must reckon with a stark new reality: our traditional, perimeter-based protective controls are fundamentally weakened.

To survive this “post-Mythos” era, security teams cannot rely on iterative improvements. Instead, we must question the status quo, work backward from a baseline of weakened controls, and embrace a rigorous Zero Trust architecture.

The new reality: Automated and weaponised AI

The integration of advanced AI models into cybercrime has dramatically increased adversarial firepower. Security teams are no longer just fighting human adversaries; they are fighting fully automated, highly sophisticated systems.

This evolution has transformed the threat landscape in several distinct ways:

  • Expanded cyber arsenals: Adversaries now possess an increased...
